I recently acquired a Philco Model 16 Code 126. I removed the power transformer to place heat shrink on some very badly worn and cracked wires and I think I may have messed up the wiring to the 80 tube when I reinstalled the transformer. I couldn’t determine colours on the old wires and I tried to return them to where they originally were.

I have continuity, a beep on my DMM, between pin 1 and pin 2 and it measures .4 ohms. I also have continuity between pin 3 and the center tap as well as pin 4 and the center tap. Pin 3 to the CT is 68.5 ohms and from pin 4 to the CT is 62.5 ohms.

This is a complicated radio for someone of my abilities and I was hoping someone could let me know if I rewired this transformer incorrectly with the information I posted here.

If you have 5 wires, do this:

The wires that go to thick-wire wound winding are the filament.
If you do not know what wire goes to what winding, do this:

Get an ohmmeter and figure out the two winding: the filament (fraction of ohm, only two wires show continuity) and the Hi-V (three wires show continuity of tens of ohms).
The two halves are your 62 and 68 Ohms. There should be 130 or so Ohms between the Hi-V ends.
These two ends are your plates.
The centertap is that middle.
The filament is, well, the filament.

It does not matter which of the two ends go to which plate, and how the filament winding is connected.

This is it.

Thanks Morzh. So it appears I did wire it incorrectly and I have to switch the wires between pins 2 and 4.

Measure the voltages first, just in case.

I was going to check the voltages as you suggested and hooked it up to my dim bulb. It appears I have a short. The bulb stays bright. I realize this is basic for most of you but not for me.
I have thoroughly checked my soldering and looked for any bare wiring that may cause the short and can’t see any obvious issues.
I would like to check my power transformer. I should have tested it while I had it out but I only put on the heat shrink at the time. My mistake. Can I test it while  connected in the chassis and if so what’s the procedure? 
What readings, either voltages or ohms, should I expect to get to indicate that it’s the PT that’s shorted.

[morzh]

Well...pull out every single load of the transformer. For every winding.
Unsolder if needed.
Then re-do your dim bulb.

There are three secondary windings.
Also, see if the input filter caps at the primary (#99 ?) are OK.

BTW have you recapped?

[bobclausen]

Thanks Morzh

Yes I recapped everything and replaced almost all the resistors as well. I redid #99 with .015 safety caps.
